けすに関するものである。[Detailed description of the invention] The present invention relates to a multi-purpose cage suitable for use as a culture cage for underwater cultured fish, as a fishing net for catching fish and shellfish swimming in schools in aquaculture fishing grounds, and as a cage for bait fish.
近年、ハマチ、タイ等の養殖漁業が盛になり、

種々の魚介が集つて来る。 In recent years, aquaculture fishing for yellowtail, sea bream, etc. has become popular.
In these aquaculture methods, fish are placed in large aquaculture cages and fed minced foods such as sardines to grow them. Spread bait is used to feed farmed fish and shellfish effectively according to their characteristics and appetite, but some of this feed leaks through the net and sinks, or flows out of the cage. Various kinds of fish and shellfish gather in search of the food that has flowed out of this fish tank.
本考案は、養殖用のいけすとして使用できると

のである。 The present invention can be used as a fish cage for aquaculture, and can also effectively capture the fish and shellfish that flock around the fish cage in search of food, and can also be used as a cage for the captured fish themselves. It provides a multi-purpose cage that can be used.

is suspended, a bottom net 4 is attached to the bottom of the enclosure net 3, and an opening is provided on the side of the enclosure net,
A net-like opening/closing body 5 is attached which has a tapered gutter-like shape and has a U-shaped cross section, consisting of left and right side nets and a bottom net.

等任意の形状とすることができる。 The main body of the fish tank of the present invention is about the same size as the culture fish cages normally used in aquaculture fishing grounds, and the net-like opening/closing body 5 corresponds to a lifting net installed in a fixed net for catching migratory fish. The size of the opening depends on the length and depth of the migrating school of fish.
Approximately 1/3 to 2/3 of the length of the enclosure net, and the width is 1/3 of the length of the net.
It is formed in about 2 pieces. This gutter-like shape is maintained by attaching the upper edges of the left and right nets to a tension net 6 stretched across the opposite sides of the floating frame. This net-like opening/closing body 5 can easily close the opening with the weight of a sinker (not shown) attached to the inside of the net-like opening/closing body by untying the above-mentioned mesh. In addition,
In the above embodiment, the net-like opening/closing body has a gutter-like shape, but it may have any other shape such as a side-opening door or a shutter-type movable door.

The size of the mesh of the main body of the fish tank of the present invention is selected so that the fish and shellfish that are migrating and captured in search of spilled food from the aquaculture cage cannot escape, and the floating frame 4
It is held at the sea surface by an appropriate method such as anchoring, and a weight is attached to the bottom edge of the enclosure net to maintain its shape, making it easy to install.
Can be moved. Further, in the present invention, the planar shape of the main body of the cage may be any other suitable shape such as quadrangular or circular, in addition to the octagonal shape shown in the embodiment.

定められる。 The multi-purpose cage according to the present invention can be used in exactly the same way as a conventional aquaculture cage by closing the opening of the net-like opening/closing body. It is also used as a trap net to effectively catch swimming fish and shellfish. That is, as shown in FIG.
The main body of the cage of the present invention is installed, and a guide net 8 is stretched between it and the opposing aquaculture cage 9. The guide net 8 is provided with one vertical edge on one vertical side edge of the net-like opening/closing body so that migrating schools of fish whose path is blocked are lured into the net-like opening/closing body 5 of the main body of the fish cage of the present invention and enter the enclosure net. The side edges are attached and the other vertical side edges are attached to the enclosure net of the aquaculture cage. The width and length of the guiding net 8 are determined in consideration of the width and depth of the fish school passage, the depth of floating bait, etc.
餌を求めて回遊する魚群は誘導網８により進路
を阻まれ、誘導網に沿つて網状開閉体開口部から
本考案いけす本体内に入り、一度入つつた後は、
開口部から脱出することは困難である。 A school of fish migrating in search of food is blocked in its path by a guide net 8, and enters the main body of the fish tank of the present invention through the opening of the net-like opening and closing body along the guide net, and once inside,
It is difficult to escape through the opening.
捕獲された魚が相当量に達したとき、網状開閉

所の制約の点から巻き網等が使用できず、タモで
すくい取つたり、投げ網、釣上げ等しか行なわれ
なかつたのに対し、非常に効果的に養殖漁場に集
まる魚介を捕獲することができる。 When a considerable amount of fish has been caught, the net-like opening/closing body is closed, the guide net is removed, and the main body of the fish tank is moved to an appropriate location. In this way, in the past, it was not possible to use purse seine nets due to space constraints, and the only methods available were scooping with tassels, casting nets, and fishing. You can catch the seafood that gathers.
さらに、捕獲された魚介は、他のいけす等に移
すことなく、そのまま、いけすとして活用するこ
とができ、養殖漁の給餌源としても極めて有用で
ある。 Furthermore, the captured fish and shellfish can be used as a cage without being transferred to other cages, and are extremely useful as a feed source for aquaculture.
本考案に係る多目的いけすは、上述のように養

組立が簡単等のため、養殖漁場に対して非常に効
果のあるものである As mentioned above, the multi-purpose cage according to the present invention can be used as an aquaculture cage, a fish trap net, and a cage for captured fish, and is easy to move.
It is very effective for aquaculture and fishing grounds because it is easy to assemble.
